Null results of experimental searches for the Higgs boson and thesuperpartners imply a certain amount of fine-tuning in the electroweak sectorof the Minimal Supersymmetric Standard Model (MSSM). The "golden region" in theMSSM parameter space is the region where the experimental constraints aresatisfied and the amount of fine-tuning is minimized. In this region, the stoptrilinear soft term is large, leading to a significant mass splitting betweenthe two stop mass eigenstates. As a result, the decay of the heavier stop intothe lighter stop and a Z boson is kinematically allowed throughout the goldenregion. We propose that the experiments at the Large Hadron Collider (LHC) cansearch for this decay through an inclusive signature, Z+2jb+missing Et+X. Weevaluate the Standard Model backgrounds for this channel, and identify a set ofcuts that would allow detection of the supersymmetric contribution at the LHCfor the MSSM parameters typical of the golden region. We also discuss otherpossible interpretations of a signal for new physics in the Z+2jb+missing Et+Xchannel, and suggest further measurements that could be used to distinguishamong these interpretations.
